PiPE-FITTI NG.

Specification of Letters Patent.

Patented March 6, 1906.

Application fried November 23, 1905. Serial No. 238.680.

To all whom, it may concern:

Bc it known that I, JAMES W. KELLY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Pipe-Fittings, of which thefolowing is a specification.

My invention relates particularly to pipefittings for use in connectionwith chandelierpipes 3 and my rimary object is to provide a ittin whichwi l serve as a means of connection etween a as-sup ly pi e or mainlocated above a cei ing an the c andelier-pipe depending from theceiling. The construction is adapted to permit the chandelier-pipe todepend directly beneath the supply pipe or main and to insure such asecure connection as will obviate danger of injury to the connections atthe supply-pipe in hanging or removing chandeliers.

The invention is illustrated in the accompanying drawings, in which-Figure 1 represents a sectional view of a ceiling and a supply-pi esupported above the same and equipped) With my improved fitting ada tedfor receiving a chandelierpipe; and ig. 2, a view similar to Fig. 1, butshowing the tting in section and havin connected with it the upper endof a chan elierp1 e.

n the construction shown, A represents a ceiling g A', the joists abovethe ceiling; A2, a cross member joining the joists; B, a gassupply pipeor main equipped with a T-iittin B; B2, a depending ipe-section connectewith the fitting B; lgs', my improved pipefitting, which may be termed aceiiing-pi e fitting, and B a chandelier-pipe depen ing from the fittinB3.

The fitting 3com rises in integral formation a tubular head havingperforate ears b', and a de ending tubular shank b2. The tubular hea isinternally threaded to receive the pipe-section B3, and the head issecurely fastened to the cross member A2 by means of screws or studs t.The lower end of the stem b2 is externally threaded and has screwed ontoit the internally-threaded up er end of the lpipe b4. Inasmuch as theead b iS firm y secured to the cross member Az it will be obvious thatthe fitting cannot be turned in the operation of ap lyin or removing achandelier-fixture, so tl'i'iat t ere will be no danger of disturbingthe connection between the ipe-section B2 and the fitting B. Preferab ythe u per end of the pipo-section B2 is oppositely tiireadcd to thelower end, thereby makinv the pipe-section B2 a right and left threadedunion. This enables the parts to be joined, even though the head b belocated adjacent to a joist, as sometimes happens where the center ofthe room comes at the joist. Where this occurs, the head is secureddirectly to a j oist instead of to the cross member.

From the description given it wiii be seen that the vertical ipe may besafely caused to depend directly beneath the horizontal pipe and that noinjury to the connection with the horizontal pipe can occur, whichinjury might on account of the inaccessibility of the joint prove asource of great danger, as well as a great expense in effecting repair.Heretoorc it has been common for those in authority to forbid the use ofvertical pipes depending directly from the horizontal su ply-pipe onaccount of the reat danger, and this has rendered necessary eretoforethe usc of pipes projecting laterally from the su ply-pipe and avingbends therein to provi( e the vertical section requisite for theconnection of the chandelier-pipe. Even this construction has beeninsecure, besides being more expensive and otherwise objectionable. Thenew construction -overcomes all objections, is cheap, readily applied,and perfectiy adapted to its pur ose.

at I regard as new, and desire to secure by Letters Patent, is-

1. The combination of a horizontal pipe, a pipe-section dependingtherefrom, and a pipefitting comprising, in integral formation, atubular head and shank, said head having an internal thread receivingthe lower end of said pipe-section and equipped with ears for connectionwith the frame member of a building, the shank of said fitting adaptedto project through a ceiling and provided with a. thread for thereception of a chandelier-pipe.

2. Thel combination of frame members and a ceiling beneath said framemembers, of a horizontal pipe supported on a fra-me member and equippedwith a T-fitting, a depending pipe section having screw connectiontherewith, a pipe-fitting com rising, in integral formation, a tubularhea equipped with IOO 'perfoiate ears and a. tubular shank pi'oeetngmember, thereby to prevent fot'a'tion of said throughthe ceiling, saidtubularhead swing Second named tting, for alle purpose set un internalscrew-thread connected with the forth.
